1120: Zugriff von nicht definierte Eigenschaft _stop

Question

i Problem mit bin ein Video-Player in Flash über AS3 schaffen, das Problem ist, dass, wenn ich versuche, das Projekt zu kompilieren, der Compiler-Fehler zeigt:

1120: Access of undefined property _stop. 
1120: Access of undefined property _pause. 
1120: Access of undefined property _play. 
1180: Call to a possibly undefined method Button. 
1120: Access of undefined property _prev. 
1180: Call to a possibly undefined method Button. 
1120: Access of undefined property _next. 

Und das geht so weiter, wie ich diese Objekte erwähnt habe, also bitte hilf mir, das zu lösen. und bin ein Neuling, also ein bisschen schwer für mich, den Fehler zu finden.

AS3:

import flash.events.MouseEvent;

    } 

    _soundTransform.volume = _volume; 
    _netstr.soundTransform = _soundTransform; 
} 

Init(); 
SetupVideo(); 
SetupButtons(); 

Und auch habe ich konvertiert diese auf Tastensymbole Objekte.

Answer 1

Wahrscheinlich vergessen Sie Instanznamen für die Objekte zuweisen, die als _stop verwendet, _pause, _play Tasten usw.

Und auch Flagge in den Eigenschaften in der Bibliothek, die „für die Actionscript-Export“ überprüfen.
